Topeka, KS Accessory Structures: Carport Rules (2026)

Topeka Municipal Code Chapter 18.60 (Density and Dimensional Standards), Section 18.60.020, governs the placement and size of carports as accessory structures in residential districts. A detached carport may not be located in a required front yard or beyond the front face of the principal building - whichever is more restrictive - and a 20-foot minimum setback applies from all street rights-of-way for roadside stands, garages, and carports. The Planning Director may administratively reduce that setback if construction is compatible with the neighborhood, available sidewalk land, right-of-way needs, and block-face location. An unenclosed carport situated less than six feet from the principal building may extend to within three feet of a side property line, providing a relaxed side-yard standard for attached or near-attached carports compared to enclosed accessory buildings. No accessory building - except a carport - may sit closer than six feet to the principal building or to another accessory building on the same lot. Maximum height for accessory buildings and structures is 15 feet when the principal building is one story and 20 feet when the principal building is two or more stories. Building, electrical, and structural permits are administered by the City of Topeka Development Services Department and follow the building codes adopted under TMC Title 14, currently a version of the International Residential Code. Local historic districts (e.g., the Potwin Place, Holliday Park, and Old Town historic districts) may require additional review by the Topeka Landmarks Commission before a new carport is built.
